A radiation image sensor 10 comprises two optical members 12, 14; a scintillator 18 deposited on entrance end faces 12a, 14a of the optical members 12, 14; a plurality of light-guiding optical components 22; and a plurality of CCDs 20. Each of the optical members 12, 14 is an optical member in which several millions/cm<2 >of optical fibers are disposed parallel to each other and integrally molded, whereas the optical fibers have an axis forming an acute angle with the entrance end face 12a, 14a. The two optical members 12, 14 are arranged such that the optical fibers respectively constituting each of the optical members 12, 14 have a gap therebetween widening from the entrance end face 12a, 14a side to the exit end face 12b, 14b side. Respective side faces 12c, 14c of optical members 12, 14 are formed with ground surfaces 12d, 14d in which the respective side faces 12c, 14c of optical members 12, 14 are ground against each other. |
